原位调控细菌纤维素微凝胶孔径构建抗高表活"岛-链"触变网络
In-situ Pore Regulation of Bacterial Cellulose Microgel for High-surfactant-resistant"Island-Chain"Network
摘要
Abstract
In this study,hierarchical-pore bacterial cellulose microgels(BC-microgel)were prepared via methods including CaCO3 content regulation(0～1 200 mg/L),particle size screening(0.5～100 µm).Then,AEO/BC-miccrogel/HPMC composite systems were constructed by combining with hydroxypropyl methyl cellulose(HPMC)and fatty alcohol-polyoxyethylene ether(AEO).The results showed that when the CaCO3 content was 300 mg/L and the particle size was 15 µm,the microgel structure with an average pore diameter of 3.17 µm could be formed.At this point,the"island-chain"network was stable and the yield stress of the composite system reached 0.89 Pa,and the thixo-tropic loop area increased to 0.58 Pa/s.Excessive CaCO3 or improper particle size lead to disorder in pore structure and deterioration of per-formance.This study elucidated the structure-activity relationship between pore size regulation and network performance,thereby providing a theoretical basis for the functional development of high-concentra-tion surfactant systems.关键词
